13 Keep your servant also from willful sins; may they not rule over me. Then I will be blameless, innocent of great transgression.
(Read Psalm 32:1-2)
Sin is the cause of our misery; but the true believer's transgressions of the Divine law are all forgiven, being covered with the atonement. Christ bare his sins, therefore they are not imputed to him. The righteousness of Christ being reckoned to us, and we being made the righteousness of God in him, our iniquity is not imputed, God having laid upon him the iniquity of us all, and made him a sin-offering for us. Not to impute sin, is God's act, for he is the Judge. It is God that justifies. Notice the character of him whose sins are pardoned; he is sincere, and seeks sanctification by the power of the Holy Ghost. He does not profess to repent, with an intention to indulge in sin, because the Lord is ready to forgive. He will not abuse the doctrine of free grace. And to the man whose iniquity is forgiven, all manner of blessings are promised.
Matthew Henry's Commentary on Psalm 19:13
Commentary on Psalm 19:11-14
(Read Psalm 19:11-14)
God's word warns the wicked not to go on in his wicked way, and warns the righteous not to turn from his good way. There is a reward, not only after keeping, but in keeping God's commandments. Religion makes our comforts sweet, and our crosses easy, life truly valuable, and death itself truly desirable. David not only desired to be pardoned and cleansed from the sins he had discovered and confessed, but from those he had forgotten or overlooked. All discoveries of sin made to us by the law, should drive us to the throne of grace, there to pray. His dependence was the same with that of every Christian who says, Surely in the Lord Jesus have I righteousness and strength. No prayer can be acceptable before God which is not offered in the strength of our Redeemer or Divine Kinsman, through Him who took our nature upon him, that he might redeem us unto God, and restore the long-lost inheritance. May our hearts be much affected with the excellence of the word of God; and much affected with the evil of sin, and the danger we are in of it, and the danger we are in by it.
